'The body or intermediate section 1 of the Wrench: isformed as ka Atube hexagonalA in cross-section. The bore of the vtubularibody is also hexagonal in cross-section and its for- Y Ward end portion constitutes a ksocket 2 adapted to'v receive a nut The bore 3 of thesleeve 4 which slidablyV fits upon lthel bodylis also. hexagonal in cross-section so that the body` isf snugly received thereinaand the `sleevegislimitedfin its sliding movementby meansofapin or other removable member 5 whioh is. passed througha ,slot formed 'in thesleeve and through lthe rear :endfportion ofa' slot 7 formedl lo: Iigitudinall'y inthe tubular `body l'andji releasably engaged'v'fith the shank Softhehandle 9. fThehandle is l'preferably formed of Woodandflthe shank thereof/is of" such 'lengththat Whentted into the rear rend portion ofthebody' itmay receive 'thepin'5, as shownin- Fig. 2sothat th'eb'ody portion will besecurelyjheldlinfengagement `fvith' 4the handley and the:v sleeve prevented from sliding forwardly beyond; a

desiredfext'ent. fWhenithe4 sleeve: is nio'ved forwardly.v its full l extent, its forward-*endV port-ion projects "from the forward; endof the body a suiiicient distance to permit of a nut beingrjreceivedin the forward? end portion ofitsbore 3' and, therefore, the forward end" portion ofjitsb'ore constitutes a socket 'adapted to receive a nutiof too'large afsifze to 'be received inthe ysocket 2Lof the body.

In'order to' engage anut" sma1'l`er .than the lnut to be received 1in the' socket '2; there'has been provided 'anAk inner 'section or A4nut-.engaging memberf 10 which is hexagonal in cross-'section andof an external diameter to ht snugly in thebore of the body portion.

.will vbe obvious that if desired .van opening to freceivethe pinf and avslot 'to refceive the pin rllcouldbe formed inthe body'l instead 'of the elongatedslot. The forward'end'portion of the lbore li'of 'the in'ne-rniit-engaging member is venlarged top rov'ideahexagonal vsocket 15 having a shoulder 16 atj'its inner 'end .-to prevent a nut fronr'being'forced'` into Vthis-socket to such an extent lthatit could be conveniently removed after havingfbeen unscrewed from. an bolt. The nut-engaging lmember 10 is Vtofbe yieldably heldin the positionsliown in Fig. 2 and, therefore, ,thereI has been provided a Spring 17 Lwhich' is :mounted in the body 1 with its forward end'abutting against'the linnerV end' of the inner` nut-enga'gingmember and its real' endl abutting the inner endof the shankS. The spring 'is held under compression bythe shank, and 2itfwill "be readily understood that the 'inneri'nutengaginghmember -will serve'fnotn only as 'a socket receive^^afsmall3iiut but also as a 5 extended forward end plunger to expel a nut received in the socket 2.

7When the wrench is employed to remove a nut from a bolt, it is grasped by the handle and the sleeve 4 projected forwardly so that it extends beyond the forward end of the tubular body. The wrench is dis nosed in axial alinement with the outer en of the bolt `carrying the nut to be removed and the y ort-ion of the sleeve placed over the nut. f the nut is of the proper size for removal by the Sleeve, it will be snugly received in the socket 3 at the forward end of the sleeve and a turning action will be exerted to loosen the nut. If, however, the nut is too small to be operatively engaged in the socket 3, the body por tion of the wrenchwill be moved forwardly through the sleeveuntil the nut tits into either the socket 2 or the socket 15. If the nut is of the proper size to be operatively received in the socket 2, `it will engage the forward end of the inner nut-engaging member and` this member will `be force( inwardly against the action ot the spring 17, so that this inner member will not interfere with the nut being `received vin the socket 2. When the nut is` removed, it is prevented from sticking in the socket 2 as lthe inner nut-engaging member will o erate as a plunger to cause it lto be expel ed from the socket. y y y In case it is necessaryto renew the' spring or make other repairs to the wrench, the pin 5 can be readily removed and the shank of the handle withdrawn. The spring and the various nut-enga ing members can then be slid longitudinal y out of en agement with each other after the pin 11 ias been removed, and the necessary repairs made or a new spring substituted fora broken one and the wrei'ieh iasily and quickly reassembled. y y

In Fig. S, there has been shown a wrench of a slightly changed or modified construet-ion. Referring to this figure, it will be seen that the tubular body 18 is hexagonal in cross-section throughout its length and that the bore of the sleeve 19 is also hexagonal 1n cross-section so that the sleeve may read- `ily slide upon the tuliiular body but will be prevented from turning thereon.` The inner nut-engaging member or plunger 20 is also of a tubular formation hexagonal in crosssection and has its inner end engaged with a spring 21 which corresponds to the spring 17 The rear end of the spring engages the forward end of the shank 220i the handle. 23 which corresponds to the handle 9 and this handle is held in the tubular body by a pin 24` corresponding to the pin 5` and passed through an opening` `25 and slot 26 formed, respectively, in the body 18 and sleeve 19. In order to prevent the inner nutengaging member or plunger from being form of wrench is, however, similar to that ol? the forni shown in Fiffs.` 1 and 2.

Having thus described the invention, I claim:

1. A socket wrench comprising a tubular body having the forward end port-ion of its bore constituting a nut-receiving socket, a. sleeve slidable longitudinally upon said body and having the forward end portion of its bore constituting a socket` to receive a nut when the sleeve is projected from the body, the rear end portion of said sleeve being formed with a longitudinally extending slot and said body having an opening registering with the slot, a handle having a shank `fitted into the rear end portion of said body, a fastener carried by said shank and extending through the opening and slot to hold the handle in place and limit sliding of the sleeve, a socket member slidable longitudinally in the forward end portion of said body and formed with a longitudinally extending groove closed at its ends, a tongue struck from said body and bent inwardly into said groove tolimit sliding of the socket member, and a spring in said body confined between the socket member and forward end of said shank and serving to yieldably resist inward movement of the socket member. y

2. A socket wrench comprising a tuliular lliody having the forward end portion o'l' its bore constituting a ruit-receiving socket, a handle having its :forward end portion fitted snugly into the rear end portion of said bodv,yan elongated socket member slidable in the forward portion of said body, means to limit sliding of the socket member in saidbody, a sleeve fitting snugly upon said body and having the forward end portion of its bore constitutinga nut-receiving socket when the sleeve is projected forwardly `from the body,` the outer face of saidv sleeve being circular `in cross-sectioi'l, said sleeve having its rearportion formed with a longitudinallyextending slot, a 4liastener for said handle projecting radiallv t'rom said body andthrough `said slot and serving to `limit sliding of the'sleeve and retain the handle in the body, and a spring in said `body between said socket member` y move`" and handle to yieldably resist inward ment of the socket member.

3. A socket wrench comprising a tubular body having the forward end portion of its bore constituting a nut-receiving socket, a handle having a shank fitted into the rear end portion of said body, means to releasably .secure the shank of said handle in said body, a socket member slidable longitudinally in the, forward end portion of the bore of said body and formed with a longi- 10 tudinally extending seat, a tongue struck from said body and bent inwardly into said seat to limit 'sliding `of the socket member longitudinally in the body, and a'spring in said body confined between the socket member and shank of said handle and serving to yieldably resist inward movement of the socket member.

In testimony whereof I afIiX my signature.
